AXLE-LUBRICATOR.'

SPECIFICATION forming part of Letters Patent No. 357,565l dated February 15, 1887.

Application led December 24, 1886. Serial No. 222,488. (No model.)

.To all whom it may concern;

Be it known that I, WILLIAM C. BANEILL, a citizen of the United States of America, residing at Ipswich, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Axle-Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to certain new and useful improvements in axle-lubricators; and it consists in the detailed construction, combination, and arrangement of the parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a vertical sectional view of my invention, andv Fig. 2 is a side elevation thereof.

In carrying out my invention I form the outer or bearing end of the vehicle-axle A with a central passage or aperture, a, which extends from the extreme outer end of the axle to a point a short distance beyond the flange against which the inner side portion of the wheel-hubis designed to bear. A smallvertical passage, al', opens into this central passage or aperture at its rear end, said vertical passage having the lower -screW-threaded end of a small lubricant or oil cup, a2, screwed therein, the object of which will soon appear. Two corresponding vertical passages, b b', are formed in the lower portion of the axle, the same being formed near the inner and outer ends, respectively, of the central passage or aperture, into which they open at their upper On the outer surface of'theax'le are formed seen that oil being first supplied in the lubricant or oil cup, the same will pass through the small passage a into the central passage or aperture, a, and out through the vertical .passage b. The movement of the wheel being in the direction of the spiral grooves will carry the oilup through the spiral groove B, and upon reaching the third verticalpassage, b2, it will pass down through the same into the central passage or aperture, and out through the second vertical passage, b, from whence it will be carried in the spiral groove B up to the said upper passage, b2, and thus continuously repeating the operation. It will be observed that the bearing end of the axle will thus be kept thoroughly oiled lor lubricated, and the oil will be reused continuously until entirely exhausted.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The herein-described axle-lubricator,con sisting ofthe bearing end having a central passage o r aperture, the vertical passages, and the spiral grooves extending from two of said passages and opening into athird vertical passage, substantially as shown and described.

2. The combination, with ,the axle having the central passage or aperture and the lubricant or oil cup, of the spiral grooves connected at their lower ends with said central passage by vertical passages and opening at their upper ends into a third passage, substantially as shown and described.

3, The combination, with the axle having a central passage or aperture andthe vertical passages, of the spiral grooves formed on the outer side of said axle, and connected at their ends with said central passage, substantially as shown, and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
